BEN BOVA- The Grand Tour Series

Has anyone read the Grand Tour series? I like the premise of the two latest Ben Bova novels Farside and New Earth but not sure I can make it through the 20+ collection of books in order to get to the two that sound interesting to me.

Any suggestions on what I can and can't miss or can I skip directly to these two books in order to get what I want?
